This chapter reports the main features of rigid carbon-polymer composite materials for electrochemical DNA biosensing. Novel approaches based on composites modified with biomolecules (biocomposites) and nanostructured materials (nanocomposites) for the improved biosensing of DNA are also discussed. 

The development of new transducing materials for DNA analysis is a key issue in the current research efforts of electrochemical-based DNA anal5Aical devices. While DNA immobilization and detection of the hybridization event are important features, the choice of a suitable electrochemical substrate is also of great importance in determining the overall performance of the anal3Aical electrochemical-based device, especially regarding the immobilization efficiency of DNA. 

The composite materials can also be classified according to the physical properties in sq/t or rigid composites.
